Patent DE-19755241-A1 (DE)
Title: Coolant compressor
Inventor: EITAI KAZUO DIPL ING
IPC: F04B27/08
Filed: 1997-12-12
Abstract: The compressor has a cylindrical body (1) with a cylindrical bore (6), a valve plate (2) mounted on one end of the cylindrical body, a cylinder head (3) containing a high pressure chamber (12) and a low pressure chamber (12) and a coolant inlet (15) and outlet (16) in the valve plate between a bore and the low and high pressure chambers respectively.

Patent DE-19802308-A1 (DE)
Title: Suction device for sand jet and fluid pressure nozzles
Inventor: LAUG HORST
IPC: B08B15/04
Filed: 1998-01-22
Abstract: During blasting work, large quantities of blasting material (granules, glass beads, slag and sand) together with residues of blasted colour coating are projected over a large area after impact with the surface being blasted. This results in the pollution of large areas of the surrounding environment. The large quantities of dust produced cause problems for the population over a much wider area. The inventive suction device prevents blasting material, dust and liquids from escaping from the blasting site and the area immediately surrounding the blast nozzle into the environment during blasting work. A second suction system which functions separately allows the device, with its integrated blast pressure nozzle, to hold itself steady automatically, even in extreme working positions, e.g., overhead, hereby relieving the operator of this task, and can still be moved laterally in any direction. The high suction capacity of the device ensures that the blasting material or liquids which rebound or are projected off of the surface during blasting work are extracted without leaving a residue and collected in containers. The inventive suction device can also be used for drying the expansion joints of concrete slabs etc. and prevents the pollution of the environment with residues of dust, joint material and chemical material.
Patent DE-19802896-A1 (DE)
Title: Integrity monitoring device for railway train

The received signals are interpreted with respect to the composition of the oscillations.  The tail vehicle feeds pressure waves with different frequencies into the compressed air line with a time offset or simultaneously. The transmitted pressure waves are evaluated with respect to their time and frequency characteristics.
Patent DE-19804673-A1 (DE)
Inventor: FUERSTNER ALOIS
IPC: C07B37/10
Filed: 1998-02-06
Abstract: The invention relates to methods for preparing macrocyclic products with 9 or more ring atoms by ring-closing diine metathesis of suitable diine substrates. The diine substrates can be converted into cycloakynes or into cycloalkadiines by cyclodimerisation, depending on the particular reaction conditions. Any alkyne metathesis catalyst can be used as the catalyst, regardless of whether they are heterogeneously or homogeneously present in the reaction medium. The preferred catalysts or pre-catalysts are transition metal alkylidine complexes, transition metal compounds which form alkylidine complexes under the reaction conditions, and transition metal compounds with metalmetal triple bonds. The method can be carried out with numerous functional groups, solvents and additives. The macrocyclic cycloalkynes or cycloalkadiines formed can be converted into numerous secondary products using known methods, especially macrocyclic cycloalkenes with a uniform configuration of the double bond, and used e.g. for synthesising epothilone or epothilone analogues.
